LS4.B-H1 | Disciplinary Core ideas
Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information–that is, trait variation–that leads to differences in performance among individuals.

Genetic Rescue to the Rescue: Preventing extinction through gene flow
Students will deepen their understanding of basic genetics concepts as they dive into real data sets from ongoing research. They will hone critical thinking and communication skills and come away with clear examples of how science can lead to positive impacts on wildlife populations.
